Over the past year and a half, CIOs and their teams have been tested like never before. In my recent IDC eBook, Understanding The C-Suite Agenda: Technology Leadership in the Future Enterprise, I argued that CIOs are unique in that no other role in the C-suite has been defined by as much rapid, continuous change and uncertainty. I also argued that no other C-suite leader has been afforded the same "bird's-eye view" of the enterprise and this rich and unique perspective is more applicable today than ever before. While the latter is most certainly true, the idea that CIOs have "seen it all" with respect to change and uncertainty may be both premature and hyperbolic.
